OHIO.

DEVICE FOR ATTACHlNG OVERCHECK=BlTS TO DRIVING-BITS.

SPECIFICATION forming part of Letters Patent No. 670,248, dated March19, 1901.

(No model.)

To all whom, it may concern.

Be it known that I, LIBERTY K. RAYMOND, a citizen of the United States,residing at Garrettsville, in the county of Portage and State of Ohio,have invented a certain new and useful Improvementin DevicesforAttaching the Overcheck-Bit to the Driving-Bit, of which thefollowing is a full, clear, and exact description, reference being hadto the accom- IO panying drawings.

The invention relates to a checkrein-bit and the means whereby it may beoperatively connected with any ordinary driving-bit.

The invention consists in a checkrein-bit having the feature ofconstruction hereinafter described and in the combination therewith ofend less flexible loops whereby to attach the driving-bit, as definitelyset forth in the claims.

In the drawings, Figure l is a plan viewof my improved checkrein-bit,the driving-bit, and the means for connecting them; and Fig. 2 is across-section thereof.

The checkreiu-bit A is of a suitable size and shape and has at its endsthe rings B B for attaching the eheckreins. In the edge of the bit-barare a plurality of (two only are shown) long narrow eyes a, throughwhich the endless flexible loops O are threaded.

The outer walls of these eyes are slotted, as

- shown, the slot at being only wide enough to permit the convenientinsertion of said loops. In fact, they are so narrow that the rubberbands must be stretched, and thereby reduced in thickness, in order tobe passed through them. These loops are preferably made of vulcanizedelastic rubber, and the drivingbit is to be passed through these, asshown in the drawings. At the right side of Fig. 1

the slotted wall of the eye is shown in the embrace of a metal sleeve D,made of very thin malleable brass,which is wrapped around said wallafter the rubber band has been inserted. Its function is to close saidslots and prevent the accidental removal of said bands.

The advantage of the construction is primarily d ue to the fact thatendless loops of rubber may be used and may be easily threaded throughthe eyes when the bits are made, or when the loops in the eyes becomeworn, or when longer or shorter loops are desired.

Having described my invention, I claim 1. A checkrein-bit havingelongated eyes near the edge thereof, the outer walls of each said eyeshaving a slit, combined with endless loops passing through said eyes andadapted to he slipped through said slits, and a driving-bit passingthrough said loops, substantially as specified.

2. A checkrein-bit having elongated substantially rectangular eyes nearits edge, said eyes having slits through their outer walls, combinedwith flat endless rubber loops passing through said eyes and adapted tobe slipped into said eyes through said slits, and a line-bit passingthrough said loops, substantially as specified.

- 3. The combination of a checkrein-bit having near one edge a pluralityof eyes having their outer walls slitted, endless flexible loops 7othreaded through said eyes, and thin metal sleeves Wrapped around theslitted walls of said eyes and closing the slits therein, and a drivingbit passing through said flexible loops, substantially as specified.

In testimony whereof I hereunto alfix my signature in the presence oftwo witnesses.

LIBERTY K. RAYMOND.
